It has been mind-buggeringly hot and humid for most of the last week, breaking records for mind-buggeringly hot heat here in the UK. But now, with heavy rain and gloom and a delicious green light filling the kitchen from the trees and bushes outside in the garden, it not only feels refreshingly cooler but looks it, too.

During this last week, almost the only way I could bear to be outside at all, was sitting on our lawn in the shade of the gorgeous hazel tree that dominates the garden.

In so many countries, trees are planted to provide shade whether it be for travellers, or for residents in towns and villages or city squares.

They understand the value of the shade the trees provide in hotter climates, but in the UK we, and by that I mean governments and entrepreneurs and business people, we seem to be obsessed with cutting down trees, almost for the sake of it.

Yet we can no longer pretend we have no idea how vital trees are; for us, for the ecosystem, for the planet. We need them to remove the carbon from the air and to replenish oxygen. They are habitats for huge numbers of wildlife. Their roots help bind and provide stability to the soil, preventing erosion, landslides, and the spread of deserts. Where they exist in sufficiently large numbers the water vapour they give off helps to bring down local temperatures and increase rainfall.

They are sources of food for animals and for people, and for thousands of years their wood has been used for building dwellings, making furniture and utensils, fencing, tools, boats and wagons, and as a beautiful raw material for artworks.

And they soothe the soul!

Used intelligently and sustainably, they will continue to perform this role for as long as we wish.

Yet despite all we now know, we continue to cut down trees at a ridiculous rate. In Brazil, we are losing rainforest now the size of three football fields per minute! The rainforest in Indonesia is also being cut down at a rapid rate. The HS2 rail link planned for the UK will cost a stupid amount of money and destroy massive amounts of woodland, just to take a little time off rail journeys that already happen.

Yet there are many smaller – petty – instances of trees being cut down that amount to official vandalism, no less. I feel particularly strongly that in many towns in the UK it has long been the policy that when trees planted along streets have become larger than the council thinks appropriate, they cut them down but rarely if ever replace them with new, younger, ones.

The call to re-wild areas of the UK is growing, and I feel we should now be devoting as much land as possible to the creation of new woodland, as well as re-planting hedgerows to replace fences, and individual trees in gardens and parks and along roads.

And stop cutting them down!
